There is scant data on the association between AD measured within the descending thoracic aorta and CV outcomes.Objective: We evaluated the association of AD at the descending thoracic aorta (AD desc) with the primary outcome of all-cause mortality, myocardial infarction (MI), stroke or coronary revascularization in patients referred for a cardiovascular magnetic resonance (CMR) study.Methods: 928 consecutive patients [(mean age 60 ± 17; 33% with prior cardiovascular disease (CVD))] were evaluated. AD desc was measured at the cross-section of the descending thoracic aorta in the 4-chamber view (via steady-state free precession [SSFP] cine sequences) and was grouped into quintiles (with the 1st quintile corresponding to the least AD, i.e., the stiffest aorta). Cox proportional-hazards regression analysis were performed for the primary outcome.Results: A total of 315 patients (34%) experienced the primary outcome during a median (25% IQR, 75% IQR) follow-up of 5.0 (0.56, 9.3) years. A decreased AD was significantly associated with hypertension, diabetes, renal disease, and dyslipidemia (p < 0.0001). A primary outcome occurred in 43% of patients with AD desc ⤠median compared to 25% with AD desc > median, p < 0.0001, and in 44% of patients with AD desc in the 1st quintile compared to 31% with AD desc in the other quintiles (p = 0.0004). Event free survival was incrementally reduced amongst quintiles (p < 0.0001). However, AD desc ⤠median was not an independent predictor of the primary endpoint after multivariable adjustment in the overall population [adjusted HR 1.09 (95% CI:0.82â 1.45), p = 0.518] or in the subgroup analysis of patients with or without prior CVD.Conclusion: In this real-world cohort of 928 patients referred for CMR, AD desc is not an independent predictor of CV outcomes.Keywords: cardiovascular magnetic resonance, aortic distensibility, descending aorta, AD, CMR |
